CHURN.

SPECIFICATION forming part of LettersPatent No. 427,053, dated May 6,1890.

Application filed February 4, 1889. Serial No. 298,612. (No model.)

To aZZ- whom it may concern.-

Be it known that I, JESSE M. (JURTICE, a citizen of Louisville, in thecounty of J efferson and State of Kentucky, have invented certain newand .useful Improvements in Ohurns; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to an improvement in churns, and more particularlyto such as are known as working-body or rocking churns without dashers,and has for its object to produce a churn of this character which shallbe simple in construction, yet substantial, and one in which theoperation shall be easy and effective.

A further object is to so construct the body of the churn that it shallbe supported at its ends, the supports being connected to the frame atpoints near the center of the churnbody, whereby an oscillatory andswinging motion is obtained.

A further object is to provide a churn in which the body shall be somounted that it may have an oscillatory motion imparted to it, and thatthe contents of the churn in seeking its level will tend to maintain thebody horizontal, when the mechanism is at rest, without the aid ofweights or similar devices.

A further object is to provide a churn in which the motion of thecontents will assist in the operation of the churn, and in which theleverage is so arranged that there will beno lost motion or power, andthat only a small portion of the contents has to be raised at one timeby the power, thereby making the operation very easy. 1

Vith these objects in view my invention consists in certain novelfeatures of construction and peculiar combinations and arrangements ofparts, as hereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of thedevice. Fig. 2 is a vertical cross-section. Fig. 3 is a detached View ofthe band-wheel and attached parts. Fig. 4 is a detached plan view of thetreadle. Fig. 5 is a view of a modification of the treadle; and Fig. 6is a view in side elevation,

ing secured between said standards near their base. The base-supports CLand standards Z) Z) are provided with perforations to align with thelongitudinal grooves c, madein the edges of the cross-piece 0. Metalrods 0 are passed through these grooves and perforations and provided atone end with heads and at the other end with suitable nuts, by means ofwhich rods the lower portion of the frame is securely held together.

' Placed between the uprights Z) b above the cross-piece c is a bar cl,having grooves in its edges for the reception of rods d, which latterpass through perforations in the standards I) Z), and are provided withheads on one end and nuts on the other. A metal plate or bracket B isinserted between one end of the bar d and the standard I), havingnotches d in the top and bottom for the accommodation of the rods d. Theportions of the plate which bear against the side faces of the bar (1are furnished with notches e, and in line with these notches aperforation is made through said bar for the reception of a pin 6, whichprojects beyond both sides of the bar (1, and upon which the treadles Care mounted. The treadles C are notched at one corner for theaccommodation of bosses f, having recesses j", which project from theplate or bracket 13. Secured to the inner edge of each treadlel is aplate f adapted to project into the notches of the bosses said platesbeing provided with perforations to permit the passage of the pin 6. Bythis construction it will be seen that the treadles will be permitted tohave a free vibratory movement 011 their pintles, but prevented from aside or wabbling motion and consequent rattling of the treadles duringthe operation of the churn.

Secured to the top of standards I) b are brackets g g, of any preferreddesign. The ends of fourrodsD areloosely connected with the brackets gg, two to each bracket. The body E of the churn is provided on itsbottom at or near each end with plates h, corresponding in number withthe rods D, and

having lugs or ears thereon to produce notches h. The free ends of therods D are bent to produce square cornered hooks 7L2,

whichare inserted in the notches 71. of plates it. Thus it will be seenthat the body E is supported from the brackets g g by means of the rodsD, and that said rods are connected with the churn-body at or near itsends.

A segment G, which may be semicircular, as shown, or a complete wheel,if desired, is provided with a central perforated boss 2' for thereception of a shaft 'L", upon which it is adapted to have anoscillatory motion, said shaft being fixed at one end in the standard 3)near its top.

Projecting centrally from the broadened rim of the wheel G is a lug 7'.A strap of leather or other suitable material II is placed upon the bandwheel and its ends allowed to hang downwardly from eachside, aperforation being made in the strap for the reception of the lugj on thesegment G. The strap H is furnished near its extremities withperforations it for the reception of the upper hooked ends of two rodsI. The lower ends of the rods I are passed loosely through perforations1, made in the front ends of the treadles, and nuts or washers aresecured upon the lower extremities of said rods; or the ends of the rodsare bent to prevent them from pulling through the perforations in thetreadles.

Projecting from the boss i of segment G is an arm J, bifurcated at itsfree lower end to receive a headed rod Z on the churn-body E, said pinbeing located in the side face of the body centrallybetween its ends andnear the bottom.

It will be seen that when the segment G is turned on its shaft theforked arm will by its engagement with the rod Z cause the body to makea longitudinal movement and at the same time an oscillatory movement onits axis. \Vhen the body is thus tilted, the weight of its contents willtend to bring it back to alevel, and the flow of the contents will carryit beyond a horizontal position. The segment G is now oscillated in thereverse direction to that above described, and consequently thechurnbody ismoved and oscillated in the reverse direction. During theoscillation of the body rod Z will describe about two-thirds of a circleand the churn-body will incline at an angle of about fort eight degreesin opposite directions. Again, when the churn-body is tipped to theright nearly all the weight of the body and contents will be on onepairof the rods D; but enough will be to the left of where rods D areattached to the ends of the body to cause the body to swing back to alevel, and the momentum of the contents will cause the contents to rushbeyond the center, thus helping to tip the body to the left, and so onduring the operation of the churn. More than half the contents arealways resting on two of the four rods D, so that the arm J never has tolift as much as half the weight of the contents of the body.

A handle M may be attached to any convenient part of the body, ifdesired.

In cases of very wide churns the treadlc mechanism shown in Fig. 5 willbe adopted. In this construction the treadles will be reduced to aboutone-half the width of the treadles shown in Figs. 1 and 3 and extendedto the front end of the churn-frame. Footplates L, provided withperforated ears 'm, are located at the free ends of the treadles andpivoted thereto by means of a belt 072/, passing through said lugs andthe treadles. The rodsI are attached to the plates L through perforatedlugs 02, projecting from the footplates L.

Slight changes might be made in the constructive details of my inventionwithout departing from the spirit thereof or limiting its scope; hence Ido not wish to limit myself to the precise details of constructionherein set forth; but,

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
